I have pretty IWC Cal.83 watch, but lost the hands ( minute & hour )during repair. :-(
How can I choice or purchase the hands through the internet ?
For example the Hole size of those hands.
The length is not so difficult but the hole size is the problem.
If is there any person who know the information for Cal.83, Please let me know.
I don't know the answer to your question, but in general these were relatively standard. I also would think that a watchmaker easily could file out a hole that was slightly too small.
I'm not sure this will tell you, but you might want to check out the Fournitures (spare parts catalogs) in the IWC Vintage Catalog Project.
